ATTACHMENT FOR FAUCETS.

Application filed November 7, 1921.

To all whom it may concern:

Be it known that I,W1LLIA1\1 S. FoLAN'r,

a citizen of the United States, residing at Stoneham, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful improvement in Attachments for Faucets, of which the following is a specification, reference being had therein to the accompanying drawings My invention provides in a faucet, in addition to an axially-movable valve-member by which outflow-of liquid through the faucet is controlled, an axially movable seal or closure for the mouth or discharge opening of the faucet, whereby dust is prevented from entering into the outlet portion of the passage within the faucet, and drip from the said mouth or discharge opening is prevented. The axially movable seal or closure coacts with a seat at said mouth or discharge opening, and is combined operatively with the axially movable valve member so that when the valve is opened to permit outflow of liquid the seal or closure is separated from its seat, to permit flow of the liquid out through the mouth or discharge opening, and when the valve is closed to stop the outflow a spring interposed between the axially-movable valvemember and the seal or closure causes the latter to cooperate with its seat to close the mouth or openingand thereby exclude dust and flyings and retain drip.

An illustrative embodiment of the invention is represented in the drawing, partly in elevation and partly in section. The in vention is shown applied in connection with the well-known lVheaton faucet.

In the said illustrative embodiment, the valve and the means and manner of actuating its axially movable member are sub stantially as heretofore. That is to say, the said movable member, marked 1, is arranged to coact with the valve-seat 2 that is provided upon the upper rim of the annular member 3, the latter being in screwthreaded engagement with the main part 4 of the faucet-body. This annular member 3 is in this instance of a special shape adapted to facilitate the application of the features of the invention to the main parts of the faucet. The stem 1 of the said valve-member 1 has combined therewith the usual expanding coil-spring 5 acting with a tendency to keep such valve-member Serial No. 513,307.

pressed into contact with the valve-seat 2. The valve-stem is made with a hole 1 that is occupied by a finger 6 projecting from a rocker 7 mounted to turn in the bearing portion 8 of the saidmain body-part 4, and the said rocker is furnished with a handle 9 by means of which the rocker may be rocked to move the valve-member 1 away from the valve-seat.

The delivery end of the faucet is constituted, in the case of this embodiment of the invention, of an annular nose-piece 10 that is in screw-threaded engagement with the intermediate annular member 3, the said nose-piece having at its mouth 11 an internal annular seat 12. The mouth 11 constitutes the discl1arge opening of the faucet. At 13 is an axially movable seal or closure member which coacts with the seat 12 for the urposes of the invention. This seal or cosure is shown as having a beveled shoulder 14: to fit said seat and coact therewith, the outer portion of the said member being adapted to occupy and practically fill the said mouth when such member is closed against the seat. For the actuation of this seal or closure member 13 it is connected with the valve-mechanism so as to be actuated in unison with the movable valve-member 1, in this instance by means of a stem 15 projecting axially from valvemember 1 and entering a chamber within the inner portion of the seal or closure member. The lower end of the said stem 15 is formed with a head 15 providing a shoulder or enlargement above which the stem is surrounded by a collar 16 that is screwed into the said chamber in the seal or closuremember 13. The space within the chamber below the said head allows for movement of the head within the chamber, thus providing for relative movement between the seal or closure-member and the stem 15 lengthwise of the said stem. In order that the seal or closure-member may be pressed with yielding force against the seat 12, an expanding coil-spring 17 is placed upon the stem, between the said collar 16 and the nut 18 at the underside of the movable valvemember. WV hen the valve-member is moved to close it against the seat with which it coacts, pressure transmitted through coilspring 17 causes the seal or closure-member 13 to bear against its seat, the stem 15 sliding through the central opening of collar 16 in the final portion of the movement of the valve-member 1 afterthe seal or closure-member 13 has brought up firmly against the said seat. When the valve-member is moved to separate it from its seat, the head 15 u on the lower end of the stem acts against t e underside of collar 16 to separate the seal or closure-member from its seat 12. Fins 19, 19, projecting inwardly from the shell of the nose-piece keep the seal or closure-member properly centered. Through the employment of a seal or closure-member o ratively combined with the movable va ve-member of a faucet, the space within the faucet-body or lip at the delivery side of the valve is closed at the mouth thereof so that while the movable valve-member remains closed dirt and flyings cannot enter the deliver portion of the faucet, and drip of the liqui which remains clinging to the inner surface of the said portion of the faucet cannot occur.

The invention is particularly useful in the case of faucets used in connection with tanks mounted on delivery wagons from which deliveries are made to customers in measured uantities; and so far as the prevention of iirip is concerned is especially of value in the case of viscid liquids such as the medium and heavier grades of lubricating oils.

Heretofore, in the case of delivery wagons such as just mentioned, it commonly occurs that as the wagons are being driven along streets and roads from one customers station to another dust and other flyings enter within the nozzles or lips of the faucets used in dispensing the contents of the tanks and become lodged therein, with the result that the lubricating oils, etc., subsequently dispensed through such faucets become charged with dirt and impurities comprising, usually more or less grit. Obviously this is a serious drawback, which my invention 01)- viates by closing the mouth or discharge opening of a faucet completely so that dust, etc., cannot enter. In the case of thick viscid liquids such as various grades of inbricating oils, more or less of the liquid remains adherent to the inner surface of the wall of the passage through which the liquid flows after passing the valve of a faucet, after the valve has been closed and the flow shut off, and thereafter such portion of the liquid drips more or less continuously for some time from the month of the faucet. This is inconvenient and objectionable, for obvious reasons. My invention prevents the drip and obviates the objectionable incidents thereof.

What is claimed as the invention is,--

1. A faucet haying combined with an axially-movable valve-member, a seat with which said valve-member coacts, and a mouth or discharge opening for the outflow of liquid, a seal or closure-member which is also axially movable for fitting a seat in connection with such mouth or openin a stem projecting axiall from the said va vemember, with the sai seal or closure-member loosely engaged with the said stem, whereby said seal or closure-member is lifted from its seat in unison with the lifting of the said valve-member from its seat, and a coil sprin confined between said valvemember an closure-member whereby the seal or closure-member is yieldingly pressed against its seat.

2. A faucet having combined with an axially-movable valve-member, and a seat with which said valve-member (-oacts, a supplemental shell or casing combined with the delivery end of the faucet body and having a discharge opening for the outfiow of liquid passing the said valve, an axiallymovable seal or closure-member for fitting a seat in -connection with such discharge opening, loosely connected with the said valve-member so as to be lifted from its seat by lifting movement of the valvemember, and a spring interposed between the valve-member and seal or closure-member by which the latter is held to the seat last mentioned.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM s. FOLANT.
